概括

转基因从转基因玉米已经传播到墨西哥的本土土地品种,甚至在没有授权种植的地区. 它们的存在在北方更为普遍,但并没有显著改变种子形态.

科学领域:

农业科学农业科学
遗传学是一个遗传学.
植物学植物学

背景情况:

墨西哥对转基因玉米的种植进行了暂停,但进口了大量的玉米.
玉米陆地品种和teosinte与转基因品种密切相关.
种子交换和迁移可能有助于转基因传播.

研究的目的:

调查墨西哥玉米陆地品种中转基因的存在和水平.
评估转基因对当地玉米品种和相关物种的影响.
为了比较在经授权种植和未经授权种植的地区的转基因存在.

主要方法:

从墨西哥中部和北部进口3204个玉米的分析.
在有或没有历史授权种植转基因玉米的地区采样.
检查转基因存在和种子批量的潜在形态变化.

主要成果:

在墨西哥所有采样地理区域检测到转基因.
转基因存在在来自北方地区的胚胎质中更为频繁.
在经授权实地试验的地区,没有证据表明转基因水平更高或种子形态更改.

结论:

转基因已经在墨西哥的玉米地产品种中传播,不管有没有种植许可.
传播似乎是无意的,可能是通过种子交换或迁移.
目前的转基因水平并没有导致研究的种子批量的显著形态变化.

Light Acquisition

Light Acquisition

In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Plant Breeding and Biotechnology

Plant Breeding and Biotechnology

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.
